Hi PerlMonks,

I am interested to get the output of the following perl script (p.pl) to a text file. I have tried in several ways but I always get only the first two lines and not the actual permutations. FH does not work when I write it in between print and join. Usually FH is written between print and " and it nicely works. Here it does not. I am looking forward to perlmonks for suggestions.

Here goes the script p.pl:

#!/usr/bin/perl -l
use warnings;
use strict; 
use Algorithm::Permute;
###########################################################
# Opening file to write the program's output.
################################################### 
open(FH, ">myPer .txt") or die "Cannot open myPer .txt";
########################################################### 
my @arr = qw/A B C/; 
my $N=scalar(@arr); 
my $permu=2; 
my $p = new Algorithm::Permute([@arr], $permu);
print"\n WELCOME to Permutation Analysis:\n
 All Possible Permutations of $permu Elements out of $N .i.e. $N P $pe
+rmu:\n";
print FH "\n WELCOME to Permutation Analysis:\n
 All Possible Permutations of $permu Elements out of $N .i.e. $N P $pe
+rmu:\n";
 while (my(@res) = $p->next) {
    do {print join("", @res);};}
 while (my(@res) = $p->next) {
    do {print join("", @res);};} 
close FH; 
exit 0;

Here goes the incomplete output of text file myPer .txt:
